《厦门音系》《以下简称《音系》，是罗常培先生1926年秋随鲁迅先生来厦门大学任教期间，对厦门方言进行调查研究后，于1931年写成并出版的专著。1956年，科学出版社将《音系》重新付排出版。半个多世纪以来，这部早期出版的汉语方言学专著在国内外语言学界产生了极大的影响。 “Phonology of Xiamen”, hereinafter referred to as “Phonology”, was a monograph written and published in 1931 by Luo Changpei in the autumn of 1926, following the investigation of Xiamen dialect by Mr. Lu Xun in Xiamen University. In 1956, Science Press re-arranged the phonetic system. For more than half a century, this monograph on Chinese dialects published early has had a tremendous impact on the linguistics community both at home and abroad.
